SIMULATION EXPERIMENTS ON THE TSR SYSTEM OF DIESEL AND MAGNESIUM SULFATE

Thermal simulation experiments on the system of diesel and magnesium sulfate were carried out using an autoclave operated at high temperature and high pressure in the presence of water. Properties of the gas-oil-solid 3-phase products were analyzed by some advanced analytical methods including gas chromatography, microcoulometry, capillary gas chromatography combined with a pulsed flame photometric detector (GC-PFPD), FT-IR and X-ray diffraction. The results show that the reaction can proceed at 450~550℃ to produce MgO, S, C, H₂S, CO₂, and a series of organic sulfur compounds such as mercaptans, sulfoethers and thiophenes as the main products. The reaction kinetics was also studied and the activation energy of the reaction is 58.6 kJ/mol.
